Noticed that Ecas status now shows new line added:
"We sent you correspondence on September 27, 2016. If you have not yet provided the information or the requested documents, please do so as soon as possible. Please wait until you receive the correspondence before sending us additional information, as the correspondence will outline all information that is required."
We applied for PGR certificate today at Mexico City. We carried only the printout of letter sent by embassy that is addressed to PGR. They let me know to expect the PGR letter in 10 business days, although the finger print agency told us to call in 4 business days. My wife actually talked to 5 people in PGR office today, because PGR page gives a link to a form, that you have to carry to bank for paying 150 pesos, and the link was not working. All 5 except one asked my wife to come to PGR next week, except 5th one, who said the forms are available in PGR.
My wife says fingerprinting is done at a different place, and not at PGR office. It was very tricky to find the fingerprinting office. The office location is not documented very well, anywhere.
